PPT-Inductors and Inductance

A capacitor can be used to produce a desired electric field Similarly an inductor symbol can be used to produce a desired magnetic field We shall consider a long solenoid more specifically a short length near the middle of a long solenoid as our basic type of inductor. Electronic Components Inductors & Inductance Induction In 1824, Oersted discovered that current passing though a coil created a magnetic field capable of shifting a compass needle. Seven years late Physics 2415 Lecture 22. Michael Fowler, . UVa. Today’s Topics. General form of Faraday’s Law. Self Inductance. Mutual Inductance. Energy in a Magnetic Field. Faraday’s Law: General Form. A changing magnetic flux through a loop generates an emf around the loop which will drive a current. The emf can be written:. When the current in a loop if wire changes with time, an . emf. is induced in the loop according to . Faraday’s . law. The self-induced . emf. is. Ɛ= -L(. dI. /. dt. ). Where L is the inductance of the loop. Inductance is measure of how much opposition a loop offers to a change in the current in the loop. Inductance has the SI unit of henry (H), where 1 H= 1 V(s/A).

Process in which a complex arrangement of conductors and dielectric is converted into a . Derive, from Maxwell field equations, a circuital relationship bounding voltages and currents. Give to the single terms of the circuit equation the meaning of capacitance, inductance and resistance. Explain the partial inductance concept. Section 34. To determine . mutual. inductance, we neglected the thickness of the linear conductors. . To determine . self. inductance, we must consider the finite size of the conductor. Otherwise . A generator is the opposite of a motor – it transforms mechanical energy into electrical energy. This is an ac generator:. The axle is rotated by an external force such as falling water or steam. The brushes are in constant electrical contact with the slip rings.. (. PECC. ). Coils (Inductors). Coils. Short history. Electrical Properties. Constructive elements for coils. Parameters. .
